FLEXIBLE COUPLING FOB PBESSIN G To all whom it may concern:- Be it known that I, ALEXANDER J. SOCIA, .a citizen of the United States, and a resident of Syracuse, in thecounty of Onondaga and 5 State of New York, have inventeda certain new and useful Flexible Couplin for Pressing Machines, of which the folfowing'is a specification. V

This invention relates to flexible couplings 1 for conducting a fluid under pressure, as

steam, to a movable part and is particularly adapted for use in connection with pressing machines of the type in Patent No.

1 Austin; and it has for its object a flexible coupling which is particularly simple in construction,--consists of but few parts and has a minimum of joints at which a leakage can occur, and which -joints can be readily taken up, or tightened to stop any leaka e thatdevelops without necessitating the a justment of other joints.

The invention consists of the novel features and in the combinations and'constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings, in which like characters designate corresponding parts in all the views. a

Figure 2 is an enlarge sectlonal vlew takenon' line 22 Figure 1. 95 Figure 3 is a sectional view through one of the unions. p

This flexible coupling comprises generally a pair of unions passages there- W through, one of the unions being fixed and 5 desi ed to be. arranged in substantial coaxlal alinement with a pivoted member, as the pivoted support of the pressing headof the pressing machine and the other of WhlGh is designed to be carried by, or movable rela- M tively to, the former union, as when a movable member to which a fluid under pressure,

as steam, is to be conveyed, as the pressing head, a resilient pipe connecting the epassages of the unions and being connect to the one union by 'a swivel connection arranged substantially coaxial with the pivotal axis of the pivoted support and being rigidly connected to the other union whereby the pivoted joints are the only joints that need Application filed July as, 1920.

adjustment for taking up wear of the packing.

'1 and 2 designate respectively the unions, the union 1 having an inlet passage 3 provided with a lateral branch 4 arranged substantially coaxial of the union 1 and extended through the bottom -of a recess 5 at one end of the union and further provided with a return passage 6 which opens at one end packing and into a recess 7 at the other end of the union.

The union 1 is also provided with a suitable radial nip 1e 8 for connection to the feed pipe 9 and with a nipple 10 for connection to a drain pipe 11.

The union 2 is provided with an inlet passage 12, and a return passage 13 and with threaded bores 14 and 15 communicating respectively with the passages 12 and 13. The

union 2 is also provided with a radial internal threaded passage 16 for receiving a pipe 17 for conducting the fluid under ressure, as steam,-to the. chambers 18 an the pressing head 19 of the machine and also with a threaded nipple 20 surrounding the pipe 17 and spaced apart therefrom for conv nection to the drain pipe 21 also connected,

or in communication with, the chambers 18 of the pressing head.

22 and 23 are conduits connecting the inlet passages 3, 12 and the return passages 13 and 6 of the unions, each conduit being connected to the union 1 b a swivel joint and being rigidly connected to the union 2, they being ere shown as formed with threaded ends 24, 25, which turn into the threaded bores 14 and 15 of the unions 2. These bores 14 and 15 are preferably coaxial with the vunion. A swivel joint connects each pipe 22, 23, to the union 1 and comprises a head 26 or 27 on an axial portion 28 or 29, of the p'pe'22, or 23, a packing 30 or 31 between the head 26 or'27 and the the bottom of the recess 5 or 7 and clamping means, as a cap 32 or 33, threaded on the end of .the um'on 1 against the head 26 or 27. The ipes 22 and 23 are resilient but are preferab'y formed with coils 34 therein. Also one of the conduits 23 is formed of sections which are connected by the coupling 35 of suitable construction for facilitating the assembl of the parts.

Inoperation, t e steam or other fluid. passes from the pipe 9 through the 2168 3, 4, conduit 21, pge 12, p1 17, into I pressing head 19, and returns to the pipe 21, nipple 20, passage 13, conduit 23, passage 6,

nipple and drain pipe 11., Durin movement of the pressing head upwar y and downwardly with its support 36, which is pivoted to the uprightbracket or standard 37 forming parts of the frame, the coupling swings about one axis only and any movement of the pressing head relatively to the support due to rockin of the head at 38, as.

it is pressed down h upon the cloth on the lower buck 39 of the machine, which rocking cloth or garment, is permitted fore in flexible couplings used in this and mm ar situations, leakage develo s more at one. packin than at'another, an hence on adjusting t e packings to take up the leakages, necessitates other adjustments and it has been found difficult especially by the user of the machine to make the required 'adjustments at one point without upsetting ad'ustments at'another point.

construction of this flexible coupling is particularly advantageous in that the condurts are rigidl connected to one union and packing is us .only between said conduits and the other union, so that the only ad-' justment necessary is at one union. Furthermore, any movement that has heretofore been provided in the fixed union, that is the union associated with the pressing head, is provided for in my cou ling by the resilient conduits. Although I ave shown this flex iblecouplin as double construction, that is,

as having eed and return conduits, ObVlously, it may be of a single-construction.

prising a escapes What I claim is: 1. A coupling of the class described comir of unions arranged with their axes para lel and having passages therethrough, extending in the direction of their axes, and a resilient conduit connecting the passages and'connected by a swivel joint to one union and being rigidly connected to the other union, the conduit being arranged at an angle to the! axes of the unions and the swivel joint bein arranged coaxially with the axis of one a? the unlons. a

2. A coupling of the class described comprising a pair of unions, each being formed with inlet and return. passages, and pipe connections for said passages,-a conduit connecting the inlet passages of the unions, .a conduit connecting "the return passages thereof, the conduits being connected to one of the unions by swivel oints and rigidly connected to the other union, substantially as-and for the purpose described.

3. A flexible" steam couplin of the class described comprising a pair 0% unions, each being formed with inlet and return passages,

and pipe connections for passages, a conduit connecting the inlet passages of the unions, a conduit connecting the return passages thereof the conduits being connected to one of the unions by swivel joints, and rigidly connected to the other union, each being formed with a coil therein to make the same resilient, substantially as and for the purpose specified. j i
